I'm wanting a new bag, not a quilt. Around a 20F bag. My problem is that I'm 6'0", and a little portly. Most of the regular 6 ft bags I've tried were too constraining, lengthwise, especially for hammock usage. I could fit in them, but they were too short to flex my foots. Trying them out in an outdoor store is impractical where I live. I want to save weight and packspace, so are there any suitable bags that I can get in a regular length, instead of going with a long 6'6" or even a 6'4" Montbell?
